The Minnesota Twins won 4 games to 3, giving the franchise its first World Series victory since 1924, when the team was located in Washington, D.C. and known as the Washington Senators.
The Texas Rangers have never won a World Series yet (the Yankees lost their first two series in a row). And for those who might suggest that the Washington Senators won a World Series (the Rangers relocated to Texas from Washington), that team was the second franchise that played in Washington. The original Washington Senators (which won the 1924 series) franchise moved to Minnesota to become the Twins.
The last team added to the NHL was the Columbus Blue Jackets and the Minnesota Wild. They are both expansion teams.
